2. EMERGENCY BROADCASTS
Emergency broadcasts are broadly divided into two types: Emergency EV message (Alert and Evacuation
messages) broadcast and Emergency remote microphone (rm-200Xf and rm-200X) broadcasts.
• Emergency EV message broadcasts include dual-origin EV broadcasts and single-origin EV broadcasts,
depending on the number of EV-200 units installed in the VX-2000.
• Set an emergency broadcast pattern consisting of an emergency EV message and corresponding broadcast
zones, and assign the set pattern to the remote microphone's function key or control input. When the
emergency mode is activated by way of the Emergency activation button or a control signal from the fire
alarm system, the assigned emergency broadcast pattern is recalled and used for the broadcast.
• Use the PC software to set the emergency broadcast pattern (refer to
p. 7-39 ) and assign it to the control
input or remote microphone (refer to p. 7-52 ).
